Furthermore, the terms "first," "second," and the like, are used to define elements only for convenience in distinguishing between the elements, and unless otherwise stated have no special meaning and are not to be construed as indicating or implying any relative importance.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1, the brain stereotactic head frame provided for the embodiment of the present invention comprises a frame 1 and at least two skull positioning frames 2 fixed on the frame 1, wherein the two skull positioning frames 2 are arranged at intervals and located on the front side of the eyes of the human body, and a light shielding plate 3 is connected between the tops of the two skull positioning frames 2. Through the setting of light screen 3 can shelter from the fluorescent tube of shadowless lamp, avoids patient's eye to receive the influence of strong shadowless lamp light, avoids eyes to produce uncomfortable sense.
Further, as shown in fig. 2, in order to avoid the light leakage of the shadowless lamp and the stimulation to the eyes of the human body, the light shielding plate 3 is an arc-shaped light shielding plate. Through inciting somebody to action light screen 3 sets up to curved light screen, can increase the area of shading on the one hand, further reduces light and leaks down, and on the other hand can adapt to with patient's forehead shape, has avoided shadowless lamp light to leak down from the different sides better to eyes to the human body form and protect better.
Furthermore, the two ends of the shading plate 3 are rotatably connected with the skull positioning frames 2 on the two sides. Specifically, two side walls of the light shielding plate 3 extend outwards to form rotating shafts 7, the skull positioning frames 2 on two sides are provided with insertion holes (not shown in the figure), and the rotating shafts 7 on two sides are inserted into the corresponding insertion holes and are in rotating connection with the insertion holes.
